Abstract
A light tower includes a base, an extendible mast coupled to the base, a battery pack supported on the base and including a plurality of lithium-ion battery cells, a light assembly including a plurality of light emitting diodes electrically coupled to the battery pack, a display configured to receive inputs and display information, and a controller in communication with the battery pack, the light assembly, and the display. The configured being to: receive a light intensity change input from the display, change a power provided by the battery pack to the light emitting diodes in response to the light intensity change input, and display on the display a change in runtime resulting from the change of the power provided by the battery pack to the light emitting diodes.
